PowerApps Deep Dive
- 1. PowerApps – Deep Dive @timopertila SharePoint Saturday Helsinki 28. September 2019
- 2. Kiitos, thank you our dear sponsors…
- 3. Hello! 3 Timo Pertilä Consultant, Microsoft MVP https://timopertila.com https://twitter.com/timopertila timo.pertila@digitalillustrated.com
- 4. 4
- 5. There are actually 3 different kind of PowerApps 5
- 6. Canvas / Model-driven / Portal PowerApps 6
- 8. Licensing summary (starting from 1.10.2019) 8
- 9. What does it mean in practise? • PowerApps plan required when having • Gateway(s) • Premium connectors (Azure services, PowerApps notifications, http-requests) • Common Data Service • No sense to use SQL anymore -> go with CDS if you need real DB • Daily Power Plarform API request limit for every user • Makers and admins doesn’t need any PowerApps plan 10
- 12. Example: Delegation supported 13 Give me all stores where location = Helsinki Here you are. All 5000 stores located in Helsinki 50 000 items
- 13. 14 Give me all stores location containing string ”Helsinki” Here are 500 first stores. Please find what you want by yourself 50 000 items Example: Delegation not supported
- 14. Delegation support depends on used... • Data source (SharePoint, SQL Server, Dynamics 365, CDS for Apps, Excel, Google Sheet...) • Function (Filter, Search, LookUp, Sort...) • Predicates (Not, In, StartsWith, +, -, <, <=, =...) Read: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/delegation-overview 15
- 15. 16 Do I have more than 500 items? Ever
- 16. But I have 50 000 items in SharePoint. Can PowerApps handle it?
- 17. It’s all about getting rid of delegation issues • Filter(AllStores, ‘Created By’.Email = User().Email) • Filter(AllStores , ‘Created By’.Email = varCurrentUserEmail) • Filter(AllStores , Text(ID) = varID) • Filter(AllStores , ID = Value(varID)) • Filter(AllStores, Created > Today() - 7) • Filter(AllStores, ‘Created time as number’ > var7DaysAgo ) 18 2019092120190922
- 18. Demo
- 19. What datastorage I should use?
- 20. 21 SharePoint list • Familiar for makers • Easy to build row- level security • Easy to work with attachments • Free • Limited support for delegation SQL Database (Azure) • Search can be delegated • ”unlimited” • Uses shared connections • Cheap • Can be extended with views and stored procedures • Goodbye citizen developers! Common Data Service • Best parts from both SharePoint list and SQL Database • Not free either cheap Top 3 datasource options
- 22. Check & to do • Minimize stuff loaded on App OnStart • Use concurrency when loading data • Avoid dependencies between screens • Expensive operations located • In ForAll • In Gallery • Delegation warnings 24
- 23. Check & to do • Save / update several items -> Use Flow • Use galleries when suitable • Use components when suitable • PowerApp might run extremely slow on older mobile phone • Reduce number of screens • Reduce number of controls 25
- 24. “Yes yes, it is a great tool. But all these PowerApps looks like SH!&#”
- 25. Lessons learned
- 27. 2. Find out what mobile devices end users use Image: Jorge Barrios
- 29. 4. Power Platform is much more than mobile app built on top of the SharePoint lists
- 30. 5. Start planning governance now
- 31. Thank You! 33 Timo Pertilä Consultant, Microsoft MVP @timopertila https://timopertila.com timo.pertila@digitalillustrated.com
